WMC08P22K

The WMC08P22K is a Type WMC polyester film/foil capacitor from Cornell Dubilier Electronics (CDE). It offers a capacitance of 0.22 µF with a ±10% tolerance and a voltage rating of 80 VDC. The capacitor features a non-inductive, extended foil construction with polyester film dielectric, housed in an axial lead package. The leads are tinned copper-clad steel, suitable for automatic insertion.

Key electrical specifications include a dissipation factor of 0.75% maximum at 25°C and 1 kHz, insulation resistance of 30,000 MΩ·µF (100,000 MΩ minimum), and dielectric strength of 250% of rated voltage for 1 minute. The part is rated for high pulse applications with a dV/dt capability of 1500 V/µs based on its body length. Operating temperature ranges from -55°C to 125°C, with full rated voltage at 85°C derated linearly to 50% at 125°C.

This capacitor is designed for use in high pulse, dV/dt circuits, and is available in tape and reel packaging for automated assembly. The axial package facilitates easy through-hole mounting on printed circuit boards.
